Application filed July 24, 1903. Serial No. 166,801.

To all whom it may cor/(rem:

Be it known that I, IIARRISON l). FLEGEL, a citizen of the United States, and resident of Racine, in the county of ltacine and State of Wisconsin, have invented certain new and useful Improvements in Indicators; and I do hereby-declare that the following is a full, clear, and exact description thereof.

My invention has for its object to provide simple, economical means for indicating the turns of waiting patrons in barber-shops and other places where checks are employed to designate the order in which patrons are to be served. Hence said invention consists in certain peculiarities of construction and combination of parts hereinafter particularly set forth with reference to the accompanying drawings and subsequently claimed.

Figure 1 of the drawings represents a rear elevation of an indicator in accordance with my invention, Fig. 2, a sectional view of the same indicated by line 22in the first figure, Fig. 3, a plan view of a portion of the indicator partly in horizontal section, this View being indicated by line 33 in the first figure, and Fig. 4, a front elevation of a fragment of said indicator.

Referring by letter to the drawings, A indicates the base, and B the back of my indicator. Exposed on the back B is a ring, C emblazoned with numbers in ascending order at'regularintervals, and the space left in the ring may be utilized for the display of advertisements. The ring herein shown is sealed for numbers from one to twelve inclusive, but it may be scaled to include numbers from one to any higher denomination than twelve in ascending order.

Extending rearward from the back B is a shelf D, and fastened on the shelf, b screws or other suitable means, is a bracli et that comprises a pair of standards E, these standards being made to serve as bearings for an arbor F that extends through said back axially of the ring C, and fast on the outer end of the arbor is a pointer G-that traverses said ring, Rigid on the other end of the ar hot is a crank H, and adjustably secured on. the crank, by means of a set-screw b, is a counterweight I for the pointer.

Between the standards E, a air of ratchetwheels J, K, are made fast on t e arbor F, the set of these wheels being such that the teeth of one are opposite those of the other with which they break joints, and the number of teeth in each of said whccls correspond with the nui'nbcr-spaccs of the ring (3 above specillngnging the ratchet-wheel J is a detentlug c, of a lever [A in pivotal connection with a standard .\l fast on the shelf 1), and in like connection with the lever is a pawl N that engages the ratchet-wheel K, said lever being provided with a lug supporting a leafspring (1 that bears against the pawl. A spiralspring P connects the lever L with the shelf 1), and to prevent ovcrrunning of the pointer G, a lcaf-springfis arranged in connection with a lug g of one of the standards E to bear against the arbor F aforesaid.

The lover I; carries the armature Q of an elcctro-magnct It fastened on the shelf D, and the recoil of the armature is limited by a set-screw h engaging a horizontal extension i of raid standard.

An audible electric signal, such a bell S, is made last on the back B, and this signal, the elcctro-magnct It and a battery T are put in electrical-conncction with one or more push-buttons U, it being intended in a barber-shop or other place where there are sevcral workmen or attendants that a pushbutton shall be arranged convenient to each of said workmen or attendants.

In practice 'the closing of an electric-circuit, by means of a push-lmtton, will result in an'cncrgization of the audible signal and electro-magnet, the attraction of the armature of said magnet causing the lever ii to tilt against resistance of the spring P, where by the detent-lug c ol'said lever is disengaged from the ratchet-wheel J simultaneous with a liftof the pawl N to engage another tooth of the ratchet-wheel Ii, so that when the pushbutton is released there will be an automatic partial rotation of the arbor 1*, due to a like return of the aforesaid lever to normal position, as a result of a contraction of the spring. Hence the pointer l will be moved one numbered space on the ring U, and the number then under said pointer will be that of the next person to be served.

Ilaving npw fully described my invention what I claim as new and desire to cover by Letters Patent, is:

The combination in an indicator of a dc vice having numbers displayed thereon in ascending order at regular intervals of a circle, a step-by-step rotary adjustable pointer for the numbers. an audible electric-signal.

is again opened the signal and magnet are cut-out and the aforesaid lever automatica spring-controlled lever, an armature on the lever, an electro-magnet opposing the armature and in circuit with the signal, a ratchetwheel rigid on a suitably mounted arboi to which the pointer is attached, a pawl engaging the ratchet-heel and connected to said have hereunto set my hand at Racine in the lever, and a normally open push button county of Racine and State of l/Visconsin in closer for said circuit, the closing of the eirthe presence of two Witnesses. cuit resulting in an energization of the signal HARRISON D.

In testimony that I claim the foregoing I ally actuated to effect a one step movement 15
